The NOAA Space Commerce page has a news post on the Microgravity Research Competition Prize being awarded. I've covered that, so I want to mention something else that was linked there: the Space Prizes page, which has some space prize history and a section about the Microgravity competition. It also notes the following:
The Office of Space Commercialization strongly supports the use of space prizes as a means to spur commercial innovation in space. The Office is examing ways to potentially use the Commerce Department's Commercial Space Achievement Award authority to offer its own kind of space prize.
I've linked (without comment) to the Commercial Space Achievement Award page before, but I hadn't seen this link to it.
Here are some other pages that may be of interest:
